Buying Guide
FAQs
What should I prioritize when choosing an organic Pro Mix for lawn or garden use?
Look for OMRI‑listed ingredients, the presence of mycorrhizae for root health, and a balance of air and water retention. Volume matters too—larger containers reduce per‑cubic‑foot cost, while smaller bags are easier to handle. Also consider any added slow‑release fertilizers if you want longer feeding periods.
How does Premier Horticulture’s 3.8 cf Pro Mix MP Mycorrhizae differ from the 2.8 cf Pro Mix HP Loose with Mycorise?
The 3.8 cf version is formulated for organic crop growers and emphasizes superior growth and stress resistance, while the 2.8 cf mix focuses on high porosity for water‑sensitive crops and low‑light conditions. Both contain mycorrhizae, but the larger batch offers a broader nutrient profile for higher yields.
Is Miracle‑Gro Organic Outdoor Potting Mix a good alternative to Premier Horticulture’s Pro Mixes for lawn repair?
Miracle‑Gro’s mix includes a quick‑release natural fertilizer that feeds for up to two months, making it suitable for container plants and small garden beds. However, it lacks the mycorrhizal inoculants found in Premier’s Pro Mixes, which can be beneficial for establishing a resilient lawn. For large‑scale lawn projects, a higher‑volume Pro Mix may provide better value.
Which product offers the longest feeding period from its built‑in fertilizer?
Premier Horticulture’s 2 cf Pro Mix Ultimate All Purpose Compound includes a slow‑release fertilizer that feeds for up to nine months, outlasting most other mixes. The 16 qt Organic Pro Seed Starting Mixes provide up to three months of feeding, while Miracle‑Gro’s mix offers about two months.
Do any of these mixes avoid peat, and why might that matter?
Back to the Roots 12‑quart Potting Mix is 100 % peat‑free, using upcycled plant material and wood fines, which reduces the environmental impact of peat extraction. If you’re aiming for a more sustainable garden, this mix offers comparable performance without the carbon‑intensive peat component.
What added benefits do mixes with Mycorrhizae provide for lawn health?
Mycorrhizae form a symbiotic relationship with plant roots, improving nutrient and water uptake and increasing resistance to stress and disease. Several Premier Horticulture mixes, such as the 3.8 cf Pro Mix MP and the 3.8 cf Pro Mix HP Biofungicide, include these fungi, making them especially useful for establishing a strong, drought‑tolerant lawn.
How does price‑per‑cubic‑foot compare across the listed products?
While exact prices aren’t provided, larger containers like the 3.8 cf Pro Mixes generally deliver a lower cost per cubic foot than smaller 16‑qt bags. Products sold in bulk, such as Michigan Peat’s 40‑lb bag, also tend to be more economical for extensive lawn projects, whereas specialty mixes with added mycorrhizae may carry a premium for their performance benefits.
